It's not mine :-) It's the 'obvious' mathematical definition
of 'normalised'.

Hmmm. The column heading says 'conversion to B-format/FMH',
and the values are prefixed by an 'x'. This suggests that
to get FMH you have to multiply the N3D component by the
value listed. But it's actually the inverse: as multipliers,
these values convert *from* FMH to N3D. And they all include
a spurious gain factor of 1/sqrt(3).
